I know MegaSquirt is a topic that's beaten to death, but I've read all the sticky's multiple times, searched, and there's a couple more questions I've got before I dig into it myself.
First, I just wanted to fully grasp just exactly HOW MegaSquirt works. If I know how it works, it'll be easier to put together because I'll know WHY I'm putting it together.
And after all the reading and studying, I can't quite grasp how the Spark aspect of MSnS works. Being driven by a mechanical distributor, how does the MS board control the spark? It seems that unless the L28ET is running with coil packs or EDIS, there's no way to control the spark. Perhaps I'm just overlooking it, but I can't seem to see it.
Second, pretty much all the writeups I've seen are for '83 L28ET's. I'm running an '81 motor, which has the different CAS and distributor. Should that make a difference in how I wire the board?
Thanks for taking the time guys. I just want to understand it fully before I build.
